Hi! Currently getent always passes 16 as second argument to gethostbyaddr, no matter if for AF_INET6 (correct) or for AF_INET (4 times bigger than it should be). This results in getent hosts 127.0.0.1 (or other IPv4 IP) to print nothing even when there is a reverse entry. 2005-10-08 Jakub Jelinek <jakub@redhat.com> * nss/getent.c (hosts_keys): Pass INADDRSZ as size rather than IN6ADDRSZ to AF_INET gethostbyaddr. --- libc/nss/getent.c.jj 2005-09-09 22:37:44.000000000 -0400 +++ libc/nss/getent.c 2005-10-08 10:50:41.000000000 -0400 @@ -280,9 +280,9 @@ hosts_keys (int number, char *key[]) char addr[IN6ADDRSZ]; if (inet_pton (AF_INET6, key[i], &addr) > 0) - host = gethostbyaddr (addr, sizeof (addr), AF_INET6); + host = gethostbyaddr (addr, IN6ADDRSZ, AF_INET6); else if (inet_pton (AF_INET, key[i], &addr) > 0) - host = gethostbyaddr (addr, sizeof (addr), AF_INET); + host = gethostbyaddr (addr, INADDRSZ, AF_INET); else if ((host = gethostbyname2 (key[i], AF_INET6)) == NULL) host = gethostbyname2 (key[i], AF_INET); Jakub
